Description

Technical Field

[0001] This utility model relates to the field of testing equipment, specifically to a power adapter indicator light testing mechanism. Background Technology

[0002] Power adapters are power conversion devices for small portable electronic devices and appliances. Currently, the testing of power adapters requires testing whether the adapter can automatically supply power and accurately detecting whether the adapter indicator light is on to determine whether the adapter is qualified.

[0003] There is a type of power adapter that, after processing, needs to be tested to ensure that the indicator light illuminates correctly and that the adapter plug can pop open properly (the power adapter consists of an upper plate and a lower plate; the upper plate can rotate relative to the lower plate, causing the plug inside the lower plate to extend or retract; the indicator light is located on the upper plate and illuminates when the plug is powered on). Currently, the power adapter is tested manually by rotating it and then placing it on a conductive base. However, due to the low brightness of the indicator light, manual visual inspection is prone to misjudgment. Therefore, a power adapter indicator light testing mechanism is needed.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0016] refer to Figures 1-4The power adapter indicator light detection mechanism shown includes a base 1, a bracket 2, and a carrier 4. A lower lifting cylinder 3 is mounted on the base 1, and a detection seat 301 is fixedly connected to the moving platform of the lower lifting cylinder 3. A conductive block 302 is fixedly connected to the detection seat 301. An upper lifting cylinder 202 is fixedly connected to the bracket 2, and an XYZ adjustment seat 204 and a servo motor 201 are fixedly connected to the moving platform of the upper lifting cylinder 202. A gripper cylinder 203 is fixedly connected to the output end of the servo motor 201. The XYZ adjustment seat 204... A photoresistor 205 is fixedly connected to the upper part. The XYZ adjustment seat 204 can adjust the position of the photoresistor 205. The carrier 4 is provided with a relief groove 401. Positioning blocks 402 and clamps 403 are respectively provided on both sides of the relief groove 401 on the carrier 4. The clamps 403 are slidably connected to the carrier 4. A spring 404 is provided between the clamps 403 and the carrier 4. A photoelectric sensor is fixedly connected to the bracket 2. A light shield is fixedly connected to the side of the gripper cylinder 203. The photoelectric sensor, together with the light shield, can detect whether the upper plate of the power adapter can rotate normally.

[0017] The two grippers of the gripper cylinder 203 are provided with arc-shaped grooves, and each arc-shaped groove is fixedly connected with a silicone sheet. The silicone sheet can improve the gripping effect on the power adapter plate.

[0018] The detection seat 301 is located directly below the clearance groove 401. The photoresistor 205 and the gripper cylinder 203 are misaligned to avoid interference between the gripper cylinder 203 and the photoresistor 205 when the upper plate is rotated.

[0019] The positioning block 402 is provided with a positioning groove, which is used to position and place the power adapter. The positioning block 402 is fixedly connected to the carrier 4.

[0020] The working principle of this utility model is as follows: When in use, the carrier 4 carrying the power adapter is transported by an external conveying mechanism. When the carrier is transported to the testing station, the carrier 4 is locked in position by an external locking mechanism. The piston rod of the lower lifting cylinder 3 extends, and the testing seat 301 moves closer to the lower plate of the power adapter. Then, the piston rod of the upper lifting cylinder 202 extends, and the gripper cylinder 203 descends to grip the upper plate of the power adapter. Afterward, the servo motor 201 drives the gripper cylinder 203 to rotate, causing the upper plate of the power adapter to rotate relative to the lower plate. The photoelectric sensor, in conjunction with the light shield, detects whether the gripper cylinder 203 can grip the upper plate and rotate smoothly to the corresponding angle. If it can rotate smoothly, the rotation test is qualified. At this time, the plug of the lower plate of the power adapter extends and contacts the conductive block 302. Then, the conductive block 302 is energized, and the indicator light is detected by the photoresistor 205 to see if it can light up normally.

[0021] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
